- the present invention relates to an electronic device, especially to a button module with a vibration feedback and a fingerprint sensing function, a fingerprint sensing module for the same, and a control method for the same.
- the user authentication mechanism of the portable electronic devices Due to the popularity of portable electronic devices, the probability of users bringing portable electronic devices to various occasions is greatly increased. It also increases the proportion of users storing various confidential or important information in portable electronic devices. Therefore, the user authentication mechanism of the portable electronic devices has received more and more attention.
- the traditional portable electronic device uses a password as a user authentication mechanism, but the password has a higher chance of being cracked or being spied on, so the protection is low.
- the biometric identification is gradually used as a user authentication mechanism, which is difficult to crack and cannot be stolen by plying eyes. It is gradually becoming an important accessory in the portable electronic devices.
- the fingerprint identification is the current mainstream.
- a fingerprint sensor module is built in the portable electronic device to recognize the user's fingerprint, and the sensor result is used as the user authentication mechanism.
- the conventional fingerprint sensor module is integrated into one of the buttons, such as the power button, to save space.
- the user puts his finger on the button with the conventional fingerprint sensor module it only can be known by the display of the portable electronic device when the fingerprint authentication is passed.
- the user has no way of knowing whether the conventional fingerprint sensor module is recognizing the fingerprint, or whether the recognition has been completed but has not passed the authentication. After a certain period of time has elapsed, the user can finally realize that he has not passed the authentication based on the experience, and the user's time is wasted. In this case, the user spends a lot of time waiting.
- the present invention provides a button module with vibration feedback and fingerprint sensing to mitigate or to obviate the aforementioned problems.
- the present invention provides a fingerprint sensing module applying for a button module having a control unit; a fingerprint sensing unit electrically connecting to the control unit; and a vibration unit electrically connecting to the control unit and disposed under the fingerprint sensing unit, wherein the fingerprint sensing unit and the vibration unit disposed on a substrate.
- the present invention provides a button module having the fingerprint sensing module as described; a switch disposed under the vibration unit; and a keycap covering on the fingerprint sensing unit.
- the present invention provides a control method of the fingerprint sensing module as described comprising steps of: processing a fingerprint sensing and generating a fingerprint sensing result when a finger is detected; determining whether the fingerprint sensing result passes an authentication by the control unit or a host; and controlling the vibration unit by the control unit to execute a first feedback when it is determined that the authentication is not passed.
- the advantage of the present invention is that the vibration unit is overlapped and arranged under the fingerprint sensing unit in the axial direction by bending and assembling, thereby reducing the width and overall volume in the horizontal direction. Therefore, the fingerprint sensing module is easily accommodated inside the button module.
- the real-time feedback performed by the vibration unit allows the user to feel the feedback of the vibration unit through the fingers for the first time. To know in real time whether the authentication is passed, the user does not have to wait, and it can effectively enhance the user experience.

- the vibration way of the vibration unit 30 is to vibrate up and down along the axial direction in which axis that the vibration unit 30 and the fingerprint sensing unit 20 are stacked.
- the switch 40 transmits a triggered message to the control unit 10 to correspondingly execute the command that should be executed when the switch 40 is triggered.
- the button module 1 is used as a power button so that the button module 1 correspondingly executes preset instructions such as power-on, sleep, or wake-up when the switch 40 is triggered.
- a control method in accordance with the present invention for the button module 1 as described comprises the following steps.
